Usage

With promise

const solrZkcliOptions = new solrZkcli.SolrZkcliOptions(
  /* cmd */ 'upconfig',
  /* currentWorkingDirectory */ undefined,
  /* zkhost */ '127.0.0.1:2181',
  /* confname */ 'my_new_config',
  /* confdir */ 'server/solr/configsets/basic_configs/conf',
  /* clusterprop*/ undefined,
  /* solrhome */ undefined,
  /* solrdockerimage */ undefined,
  /* machineName */ 'localhost',
  /* network */ 'host',
);


solrZkcli.SolrZkCliCommand( options ).then( (data) => {
  console.log('data = ', data);
});

//data =  { ok: true }

With callback:

solrZkcli.SolrZkCliCommand( options, function (err, data) {
  console.log('data = ', data);
});
